Some 50,000 people marched in Lima on Tuesday to protest the presidential candidacy of frontrunner Keiko Fujimori, 24 years to the day after the coup d'etat staged by her father.
Shouting "Fujimori never again!" a crowd of mainly young people gathered in the central Plaza San Martin carrying banners and a giant Peruvian flag before marching to the National Electoral Board days ahead of Sunday's election.
"I want the world to know that Peruvians are outraged at the possibility that the daughter of a corrupt (leader) will be president," university professor Patricia Salazar, 57, said.
Hundreds marched in a handful of provincial cities against the conservative Fujimori, 40.
Her father Alberto Fujimori, who ruled between 1990 and 2000, was the first Peruvian president convicted of corruption and crimes against humanity -- for authorizing death squads -- in nearly a century.
Sentenced in 2009, he is currently serving a 25-year prison term.
Nearly half of the candidates for the vote on Sunday have abandoned the race or been ruled out under an electoral reform in force since January, plunging the South American country into political uncertainty.
Further disruption could come if accusations of vote-buying lead to the elimination of banker and economist Pedro Pablo Kuczynski, who is running second in the polls.
Fujimori was spared Friday, when the National Electoral Board ruled that her candidacy could move forward despite similar vote-buying accusations.
